Visual Magic A Physical World Connection Player

From The Daily Star Latest Dot pattern tech offers marketing opportunities Dot patterns, which can be presented in a very small place and in the form of very tiny dots, can possibly be printed on graphic materials without hampering the original beauty of the content, and by distributing the same pattern repeatedly over a graphical object.

The original decimal number can be retrieved by capturing the image from any portion of that printed graphic, and by analysing that captured image for the arrangement of the dots it is carrying.

"This patented technology, which is very much invisible to the naked eye, will certainly pose as a replacement for the barcode or a micro-barcode printed on a consumer product, a catalogue, an article where a cellular phone camera or a barcode scanner is used to retrieve data, such as price tags, product information, or even proof of authenticity presented within that code," Zaman said.

Considering all these data possibilities, and since each dot pattern is unique, the security characteristics presented by the pattern remains uniquely high," stated Zaman on prospects of dot pattern usage on passports or documents with such integrity

It's an interesting idea, but, among other things, it requires that a special printing process be used, and special infrared inks.

The deep problem with getting the PWC thing going is to simplify all aspects of the application so that the minimum number of things already in place have to be in any way altered. Making the printing more difficult is just one more major hurdle.

And this doesn't even get into the problem of having, presumably, to introduce a good infrared filter into the camera phone sensor.

This is not a practical solution. First it will NOT work with standard camera phones and standard printing. This idea has been widely promoted by other firms but it really needs a flatbed scanner or special camera. Further how is the consumer to know that an image is active?
